BACKGROUNDThe CRF07_BC recombinant strain has been one of the most predominantly circulated HIV-1 strains in China, it is therefore necessary and urgent to develop a relevant animal model to evaluate candidate vaccines targeting HIV-1 CRF07_BC. A highly replication-competent simian/human immunodeficiency viruses (SHIV) construct containing the Chinese CRF07_BC HIV-1 env gene with the ability to infect Chinese rhesus monkeys would serve as an important tool in the development of HIV vaccines. The aim of this study was to examine whether SHIV XJDC6431 with the env fragment from a Chinese HIV-1 isolate virus could infect the human and monkey peripheral blood mononuclear cell (PBMC), establish infection in Chinese rhesus macaque.

METHODSA SHIV strain was constructed by replacing the rev/env genes of SHIV KB9 with the corresponding fragment derived from the HIV-1 CRF07_BC strain. The infectious activity of the SHIV clones was determined in vitro in PBMCs from both non-human primate animals and humans. Finally, one Chinese rhesus macaques (Macaca mulatta) was infected with one SHIV via intravenous infusion.

RESULTSOne SHIV clone designated as SHIV XJDC6431, was generated that could infect macaque and human PBMC. The virus produced from this clone also efficiently infected the CCR5-expressing GHOST cell lines, indicating that it uses CCR5 as its coreceptor. Finally, the virus was intravenously inoculated into one Chinese rhesus macaque. Eventually, the animal became infected as shown by the occurrence of viremia within 3 of infection. The viral load reached 105 copies of viral RNA per ml of plasma during the acute phase of infection and lasted for 10 weeks post infection.

CONCLUSIONSWe conclude that SHIV XJDC6431 is an R5-tropic chimeric virus, which can establish infection not only in vitro but also in vivo in the Chinese rhesus macaque. Although the animal inoculated with SHIV XJDC6431 became infected without developing a pathologic phenotype, the virus efficiently replicated with a persistent level of viral load in the plasma. This suggested that the SHIV could be used as a tool to test candidate AIDS vaccines targeting the Chinese HIV-1 CRF_07BC recombinant strain.

BACKGROUNDSome larger scale, randomized studies have demonstrated the superiority of drug-eluting stents (DES) over bare metal stents (BMS) for the treatment of acute myocardial infarction (AMI). This study aimed to investigate the impact of DES, in comparison with BMS, on the 2-year clinical outcomes in patients with ST-elevation myocardial infarction (STEMI).

METHODSFrom January 2002 to December 2008, a total of 1301 consecutive STEMI patients treated with coronary stenting in Shenyang Northern Hospital were prospectively registered. Patients received BMS (n = 868) or DES (n = 435) implantation in the infarction related artery according to physician's discretion. A propensity score analysis was performed and two well matched subgroups were selected (BMS, n = 288; DES, n = 288) to evaluate the 2-year clinical outcomes. The primary outcome was the occurrence of major adverse cardiac events (MACE), which was defined as a composite of all-cause death, myocardial infarction (MI), or target vessel revascularization (TVR).

RESULTSSurvival salvage analysis showed that 2-year cumulative hazards were not significantly different between the two groups with respect to TVR (2.8% vs. 3.1%, log-rank P = 0.780), stent thrombosis (1.7% vs. 4.2%, log-rank P = 0.079) and MACE (8% vs. 10.8%, log-rank P = 0.236). Multivariate analysis showed that DES was an independent protective factor of MI (HR: 0.211, 95%CI: 0.049 to 0.908) and stent thrombosis (HR: 0.327, 95%CI: 0.107 to 0.994).

CONCLUSIONDES was associated with similar 2-year clinical outcomes to those of BMS for the treatment of STEMI in daily practice.

OBJECTIVETo evaluate the efficacy of Bufei Yishen Granule BFYSG) combined with Shufei Tie acupoint sticking therapy on quality of life of patients with stable chronic obstructive pulmonary disease (COPD).

METHODSA multi-center, double-blinded, double-dummy and randomized controlled method was adopted in this trial. A total of 244 patients were randomly assigned to a trial group and a control group according to the random number, each with 122 patients; treatment allocation occurred when the participants met the inclusion criteria and signed the informed consent form. In the trial group, patients were treated with BFYSG combined with "Shufei Tie" acupoint sticking therapy and sustained-release theophylline dummy, and in the control group patients were treated with oral sustained-release theophylline and BFYSG dummy combined with "Shufei Tie" acupoint sticking therapy dummy. The therapeutic course for two groups was 4 months and the follow-up was 6 months. The frequency and duration of acute exacerbation calculated by adding up each frequency and duration of acute exacerbation in treatment and follow-up time respectively, the quality of life measured by the World Health Organization Quality of Life (WHOQOL)-BREF scale and adult COPD quality of life (COPD-QOL) scale were observed.

RESULTSAmong the 244 enrolled patients, 234 were screened for full analysis set (FAS); 221 were screened for per-protocol analysis set (PPS). After 4-month treatment and 6-month follow-up there were differences between the trial group and the control group in frequency of acute exacerbation (FAS: P=0.013; PPS: P=0.046); duration of acute exacerbation (FAS: P=0.005; PPS: P=0.006); scores of physiological, psychological and environment aspects of the WHOQOL-BREF questionnaire (FAS: P=0.002, P=0.006, P=0.000; PPS: P=0.00, P=0.001, P=0.000); scores of daily living ability, social activity, depression symptoms aspects of the COPD-QOL questionnaire (FAS: P=0.000, P=0.000, P=0.006; PPS: P=0.002, P=0.001, P=0.001).

CONCLUSIONBFYSG combined with acupoint sticking therapy could improve the quality of life of patients with stable COPD.

OBJECTIVETo investigate the clinical efficacy and reliability of citalopram in the treatment of premature ejaculation.

METHODSWe included in this study 80 patients who came to our andrological clinic for premature ejaculation from May 2011 to May 2012, and randomly assigned them to a treatment and a control group of equal number to receive citalopram (20 mg/d) and placebo, respectively. We recorded the intravaginal ejaculation latency time (IELT) and sexual intercourse satisfaction scores before and at 2 and 4 weeks after treatment, and compared them between the two groups.

RESULTSIn the treatment group, IELT was significantly longer at 2 and 4 weeks than before treatment ([5.64 +/- 1.31] and [7.12 +/- 1.56] min vs [0.91 +/- 0.18] min, P < 0.01), so was it at 4 than at 2 weeks (P < 0.01), and the sexual intercourse satisfaction scores were remarkably higher at 2 and 4 weeks than before treatment (6.1 +/- 1.3 and 6.3 +/- 1.1 vs 2.5 +/- 0.8, P < 0.01), but with no significant difference between 2 and 4 weeks (P > 0.05). The control group showed no significant differences in the mean IELT and sexual intercourse satisfaction scores between pre- and posttreatment ([1.01 +/- 0.21] vs [0.95 +/- 0.17 min; 3.1 +/- 1.3 vs 3.0 +/- 1.1, P > 0.05).

CONCLUSIONOral medication of citalopram at 20 mg/d can significantly prolong IELT and improve sexual intercourse satisfaction in patients with premature ejaculation.

BACKGROUNDTo investigate the incidence and risk factors of retinopathy of prematurity (ROP) in two Neonatal Intensive Care Units in North and South of China, respectively.

METHODSWe studied data concerning 472 infants with gestational age (GA) ≤ 34 weeks or birth weight (BW) ≤ 2000 g who were admitted to the Zhujiang Hospital of Southern Medical University and the Fourth Hospital of Shijiazhuang between January 1, 2011 and December 31, 2011. Clinical information about perinatal neonates was collected and was confirmed by reviewing medical charts. The incidence and severity of ROP were assessed in the screened population. Main outcome measures are the incidence and severity of ROP. The relationship of clinical risk factors and the development of ROP were analyzed.

RESULTSThe overall incidence of ROP was 12.7%, and the overall incidence of type 1 ROP was 2.3%; 9.4% of infants in Zhujiang Hospital had ROP compared to 15.0% infants in the Fourth Hospital of Shijiazhuang developed ROP, and the difference is statistically significant. ROP was significantly associated with GA (odds ratio [OR]: 0.77 [0.62-0.95], P = 0.015), BW (OR: 0.998 [0.996-0.999], P = 0.008), maternal supplemental oxygen administration before and during delivery (OR: 4.27 [1.21-15.10], P = 0.024) and preeclampsia (OR: 6.07 [1.73-21.36] P = 0.005). The risk factors for ROP are different in two hospitals. In Zhujiang Hospital, BW is the independent risk factors for ROP while GA, BW and preeclampsia in the Fourth Hospital in Shijiazhuang Conclusions: Retinopathy of prematurity incidence is different based on area. Incidence of ROP is still high in China. More efforts need to prevent ROP.

BACKGROUNDRecent studies reported that percutaneous coronary intervention with stent implantation was safe and feasible for the treatment of left main coronary artery (LMCA) disease in select patients. However, it is unclear whether drug-eluting stents (DESs) have better outcomes in patients with LMCA disease compared with bare-metal stent (BMS) during long-term follow-up in Chinese populations.

METHODSFrom a perspective multicenter registry, 1136 consecutive patients, who underwent BMS or DES implantation for unprotected LMCA stenosis, were divided into two groups: 1007 underwent DES implantation, and 129 underwent BMS implantation. The primary outcome was the rate of major adverse cardiac events (MACEs), including cardiovascular (CV) death, myocardial infarction (MI), and target lesion revascularization (TLR) at 5 years postimplantation.

RESULTSPatients in the DES group were older and more likely to have hyperlipidemia and bifurcation lesions. They had smaller vessels and longer lesions than patients in the BMS group. In the adjusted cohort of patients, the DES group had significantly lower 5 years rates of MACE (19.4% vs. 31.8%, P = 0.022), CV death (7.0% vs. 14.7%, P = 0.045), and MI (5.4% vs. 12.4%, P = 0.049) than the BMS group. There were no significant differences in the rate of TLR (10.9% vs. 17.8%, P = 0.110) and stent thrombosis (4.7% vs. 3.9%, P = 0.758). The rates of MACE (80.6% vs. 68.2%, P = 0.023), CV death (93.0% vs. 85.3%, P = 0.045), TLR (84.5% vs. 72.1%, P = 0.014), and MI (89.9% vs. 80.6%, P = 0.029) free survival were significantly higher in the DES group than in the BMS group. When the propensity score was included as a covariate in the Cox model, the adjusted hazard ratios for the risk of CV death and MI were 0.41 (95% confidence interval [CI]: 0.21-0.63, P = 0.029) and 0.29 (95% CI: 0.08-0.92, P = 0.037), respectively.

CONCLUSIONSDES implantation was associated with more favorable clinical outcomes than BMS implantation for the treatment of LMCA disease even though there was no significant difference in the rate of TLR between the two groups.

BACKGROUNDBivalirudin was widely used as an anticoagulant during coronary interventional procedure in western countries. However, it was not available in China before this clinical trial was designed. This randomized, single-blind and multicenter clinical trial aimed to evaluate the efficacy and the safety of domestic bivalirudin during percutaneous coronary intervention (PCI).

METHODSA randomized, single-blind, multicenter trial was designed. Elective PCI candidates in five centers were randomized into a bivalirudin group and a heparin group, which were treated with domestic bivalirudin and non-fractional heparin during the PCI procedure. The efficacy was evaluated by comparing the activated coagulation time (ACT), the procedural success rate (residual stenosis < 20% in target lesions without any coronary artery related adverse events within 24 hours after PCI), and the survival rate without major adverse cardiac events at 30 days after PCI between the two groups. Safety was evaluated by the major/minor bleeding rate.

RESULTSA total of 218 elective PCI patients were randomized into a bivalirudin group (n = 110) and heparin group (n = 108). Except for two patients needing additional dosing in the heparin group, the ACT values of all other patients in both groups were longer than 225 seconds at 5 minutes after the first intravenous bolus. Procedural success rates were respectively 100.0% and 98.2% in the bivalirudin group and heparin group (P > 0.05). Survival rates without major adverse cardiac events at 30 days after PCI were 100.0% in the bivalirudin group and 98.2% in the heparin group (P > 0.05). Mild bleeding rates were 0.9% and 6.9% (P < 0.05) at 24 hours, and 1.9% and 8.8% (P < 0.05) at 30 days after PCI in the bivalirudin group and heparin group respectively. There was one severe gastrointestinal bleeding case in the heparin group.

CONCLUSIONSDomestic bivalirudin is an effective and safe anticoagulant during elective PCI procedures. The efficacy is not inferior to heparin, but the safety is superior to heparin.

BACKGROUNDCoronary stents are widely used in percutaneous coronary intervention (PCI) procedures. We aimed to explore the incidence, predictors and characteristics of stent thrombosis (ST) after coronary stent implantation in routine clinical practice.

METHODSFrom data of 18 063 consecutive patients who underwent successful stent implantation in Shenyang Northern Hospital from 2004 to 2010, we identified patients with definite ST (n = 140) and control patients (n = 280) matched on age, diagnosis, sex, current antiplatelet medication and stent type. The incidence, predictors and characteristics of ST after coronary stent implantation were investigated.

RESULTSThe incidence of angiographically confirmed ST was 0.78% (140/18 063). The time distribution of ST was acute in 43 (30.7%), subacute in 50 (35.7%), and late in 47 (33.6%) patients. Binary Logistic regression analysis identied the angiotensin-converting enzyme inhibitor (ACEI) (odds ratio (OR) = 0.472, 95%CI: 0.276 - 0.807, P = 0.006) and heparin (OR = 0.477, 95%CI: 0.278 - 0.819, P = 0.007) were associated with an reduced risk of cumulative ST. Stent length (OR = 1.042, 95%CI: 1.026 - 1.058, P < 0.001), serum creatinine total (OR = 1.020, 95%CI: 1.004 - 1.035, P = 0.04), cholesterol (OR = 1.267, 95%CI: 1.021 - 1.573, P = 0.032), glucose (OR = 1.086, 95%CI: 1.002 - 1.176, P = 0.044), and platelet aggregation (OR = 1.113, 95%CI: 1.075 - 1.154, P < 0.001) were associated with an increased risk of cumulative ST.

CONCLUSIONST is associated with longer stent length and higher level of total cholesterol, glucose and platelet aggregation.
